White-Tailed Deer White-t iled deer re one of Missouri’s most v lu ble wildlife resources bec use they provide visu l, economic, nd educ tion l v lue.

In the summer, white-t iled deer re reddish brown nd they turn gr y to gr yish brown in the winter. However, there re reports of lbino deer lso existing in Missouri. Albinism is recessive tr it in which deer l cks the gene for norm l color tion nd does not produce the enzyme responsible for skin, h ir, nd tissue color tion.

Bucks (m le deer) norm lly shed their ntlers during the l te winter e ch ye r. Once buck sheds its ntlers, new growth st rts immedi tely. The ntlers re equipped with rich blood supply nd h ve thick, h ir like covering commonly known s velvet. While “in velvet,” ntlers re living org n nd re vulner ble to injury. By e rly September, the velvet dries nd is rubbed off, le ving ntlers th t re solid nd h rd. Sever l theories ttempt to expl in the purpose of ntlers in the deer f mily. These theories suggest th t ntlers re used s me ns of defense, s sign of genetic superiority, nd to show soci l domin nce.

White-t iled deer re browsers, e ting twigs, le ves, b rk, gr sses, weeds, nd soft-stemmed pl nts. Deer m y lso e t corns nd other nuts, fruits, mushrooms, lg e, nd mosses when v il ble. M les require high-protein food during ntler growth. Fem les need high-protein diet during pregn ncy nd while nursing young.

As deer herd incre ses in number, it c n eventu lly exceed n re ’s biologic l c rrying c p city—the m ximum number of deer h bit t c n support. When deer numbers exceed the c rrying c p city, the physic l condition of the deer decline resulting in lower reproductive nd surviv l r tes. In ddition, l rge deer herds c n strip the forest of young trees nd shrubs, reducing resources v il ble to other species. The Missouri Dep rtment of Conserv tion estim ted th t the white-t iled deer popul tion w s gre ter th n one million st tewide in 2014.
